PC/104 bus connector (CN1)
The PC/104 connector is for connecting the PV-5127 to the CPU and other PC/104 boards. There
is a female connector on the top, and pins on the bottom so that you can mount other PC/104 boards
both above and below the PV-5127.
The main +5V and +12V outputs are available in the PC/104 connector, so you don’t need to use
the KL3 outputs when drawing smaller currents. The maximum allowed current through the
PC/104 connector is 2A per pin. Using all three 5V pins in parallel together with at least three
GND pins allows a maximum of 5V/6A. There is one 12V pin, allowing max 12V/2A. For larger
currents, you must use the KL3 power connector.
The ATX signals (+5V STB, PS_ON and PWR_GOOD) are not available in the PC/104 connector.
The PC/104 bus is also used for software UPS status and power-off, see the UPS Control section.
The software interface uses the following signals:
